I want to create a presence/absence matrix that has the date on the y-axes and individuals on the x-axes. When an individual was present on the particular date, the output should be 1, while if it was absent the output should be 0. I have a dataframe with the names of individuals and the dates that they are present in a group:

In total I have over a thousand individuals and their dates.

I also have a list/dataframe that contains all the dates from 2015-01-01 to 2021-31-12.

My output data needs to look like this:

Where the output is 1 when an individual was present in the group at that time and a 0 when it was not. I feel like there should be an easy solution for creating this but so far I have not managed. One of the problems I am encountering is that the list of dates is for example longer than the dataframe with the individuals, making a dcast function for example impossible.

Any help or suggestions would be greatly appreciated! Please also let me know if I should provide more code/background.

Thank you very much!

I'm trying to do RSA encryption using PHPSecLib, with a manual install (ie not using Composer).

I'm following these manual installation instructions I found here: https://davescripts.com/manual-installation-of-phpseclib

And trying to do this example which I located here: How to Decrypt RSA OAEP with SHA256 using openssl on PHP

My steps I've taken so far:

1. Visited the GitHub repository here: https://github.com/phpseclib/phpseclib/tree/3.0

2. Under 'Code' selected 'Download ZIP'.

3. Unzipped the files locally and uploaded the entire 'phpseclib' directory to the server.

4. Created a test script, and troubleshooted multiple layers of includes and use that were needed to get it working.

5. However, at the moment, I'm getting a new error - "Class name must be a valid object or a string" which I don't understand and can't seem to resolve.

My test script is now as follows:

I am trying to plot a graph and have the color of the vertices be based on either the vertex ID or the name. I use a dataset with an adjacency matrix with column names. However, even with hours of searching I am clueless how I should color these nodes. the names of the columns are:

"Mohamed.Atta", "Marwan.Al.Shehhi", "Ziad.Jarrah", "Said.Bahaji", "Ramzi.Bin.al.Shibh" and the index : 15, 13, 25, 28, 14

my code:

I am creating a kind of dictionary where a user enters an input value and the output in different languages/ways are showed in multiple different fields.

1 input can have multiple outputs. The output is already stored against specific input so if a specific input is present, its specified output is displayed

I am using the below code(s).

I want to insert some data in Table1 in my database selecting it from another Table2 but the Table1 has another attribute for username (ComputerName).

What I have tried:

With the code I can search for data without problem. But let´s say I know the "name" of a Virtual Machine, but don´t want to search for it manually, but don´t know it´s "uuid".. would it be possible that the code goes (loops?) through the whole json file (it´s deeply nested), finds that "name" and returns the "uuid"? Somewhat like this if "name" == "DEV Ubuntu 18": print("uuid") I know it´s not that simple, like above, but it serves only as explanation what I want to achieve.

In 'Core Java Volume 1', Horstmann recommends this trick from Peter von der Ahé to "purposely introducing an error ... to see which type the compiler infers for a generic method call".

For example, for:

I am trying to put a char at the end of each line in a file:

I have been able to generate the all permutation of length 4 from a string, the problem that I am facing now is that all the permutation have duplicates like {abcd) ,{adbc},{bcda}...which are all same as from Mathematical definition of set.

Is there a short version in java-8 where I can get the pure set?

My code that generated the all permutation:
